海岸带沙荒风口木麻黄无性系造林效果的综合评价

以木麻黄无性系的防护效能和速生丰产性能为基础,运用多目标决策方法,对沿海沙荒风口6种木麻黄无性系造林效果进行综合评价,结果表明:在沙荒风口造林的6种木麻黄无性系中,粤501最抗风,其防护效能最高,平18次之;平18最速生丰产,粤501其次;莆20在6种无性系中无论抗风性还是速生丰产性能均最低。综合评价指标以平18最高,粤501次之,莆20最小。平18和粤501是沿海沙荒风口造林理想的木麻黄无性系。

Comprehensive Evaluation of Forestation Effect of Casuarina equisetifoliaClone in Air Gap of Coastal Sand and Desert Belt

Based on the protective benefit,fast-growing and high-yield characteristics of forestation effect of 6 species of Casuarina equisetifolia clone in air gap of coastal sand and desert belt was evaluated by means of polygonal dicision. The results showed that in the 6 species of Casuarina equisetifolia clone, the wind-resistance and protective benefit of Yue_(501) were the strongest and Ping_(18) was second. The fast growing and high -yield characteristics of Ping_(18) was the strongest and that of Yue_(501) was second; The wind-resistance , fast-growing and high-yield characters of Pu_(20) were the lowest in the 6 species clone. The comprehensive evaluation index of 6 species clone with Ping_(18) was highest and Yue501 was second and Pu_(20) was the smallest .The suitable Casuarina equisetifolia clone planting in air gap of coastal sand and desert belt were Ping_(18) and Yue_(501).
